Abstract

The present invention discloses a method for implementing multicast in RSTP (Rapid Spanning Tree Protocol) ring network. In the method, the port mode of a program is configured to a fixed port mode, a root port binding mode or an upper layer querier port following mode; a multicast module on access equipment traverses a program table on receiving a root port switching message, updates the corresponding port of each program whose mode is configured to the root port binding mode as the changed root port; or on receiving an IGMP (Internet Group Management Protocol) QUERY packet from a port which is different from a recorded global querier port, the multicast module updates the global querier port as the port receiving the IGMP QUERY packet, traverses the program table, and updates the corresponding port of each program whose mode is configured to the upper layer querier port following mode as the port receiving the IGMP QUERY packet.
